Effect of Biological Agents (Biofresh) and Organic Matter to Progress of Soybean Mosaic Virus (SMV) and Yield of Soybean in Sub-Optimal Ultisol Land

摘要

Soybean mosaic virus (SMV) is most recognized as the source of problems for the soybean crop. This study aimed to investigate the effect of biological agents (Biofresh) and organic matter on the progress of Soybean Mosaic Virus (SMV). This study uses factorial randomized complete block design consisting of two factors i.e. biological agent (Biofresh) formulations and organic matter compost treatments. Data were analyzed using the SAS 9.1.3 version statistical softwere. The treatments were significantly different tested further by Duncan multiple range test at 5% level. Single treatment of Biofresh formulations and the type of organic matter influenced the latent period, the disease severity, AUDPC value of SMV and the soybean plants grown in sub-optimal ultisol land. The latent period symptoms of SMV applied with Biofresh formulation and organic matter were found on average of 9-11 days after inoculation. Plant height and number of leaves of soybean plants cultivated with the combination treatment of solid formulations and compost of soybean litter waste (A1C1) showed the best results, with plant height and number of leaves at 10 WAP are 49.37 cm and 26.53 sheets. Plants treated with Biofresh of solid formulation and organic matter soybean (A1C1) showed the best production with crop yields 261.00 pods, 644.33 seeds and 92.17 g seed weight. Organic matter in a solid formulations that is applied with organic matter of soybean litter waste can increase the growth and sustainability of soybean and soybean crop yields.
